I think I'm similar in that good bass is a requirement for me. I can no longer stomach headphones that have below neutral bass signatures and yet many of them get so much high praise around here for some reason.Thanks a lot for chiming in with your valuable experience!
I mostly used basscannons/basshead as a word of mouth I am not sure I am the basshead that headphone manufacturers aim for when they make stuff like the Cascade which is way too boosted in the lowend to me.
I really prefer a good thump kick midbass boost similar to what Kennerton Magni, Ultrasone Pro 900 delivers where Ultrasone Pro 900 comes out on top with the subbass being more engaging and sounding more punchy to subbass driven music.
But its hard because most headphones in that pricerange does have neutral subbass and midbass boost, I want both while retaining clarity in highs.
It sounds to me like the Denon will give more depth to the subbass (which sounds like warm to me) and Focal Radiance will have more kick/thump/attack to the midbass. Tough choice.
Then Denon will shine If you listen to music with a lot of sub bass. Here's a graph. To "audiophiles" it might be bassy and warm but it really isn't.
Here's the Radiance. It has a thicker overall sound and that boosted midbass gives it just the right amount of color for me without going from warm to muddy.
I mostly listen to the Denon when I want the clarity and separation of an open back with the bass and extension that I can't get from and open back(in my price range). The downside is the lack of a deep soundstage. If I want more bass, dynamics, and warmth, with better soundstage and layering I go with the Radiance. They're more different than similar. A good pairing.
